To all whom it may concern:

Be it known that I, JIM Laws AsHWoRTH, a citizen of the United States,and a resident of Thompson Station, in the county of Williamson andState of Tennessee, have made certain new and useful Improvements inWire-Stretchers, of which the followin is a specification.

My invention relates to improvements in wire stretching devices, and itconsists in the constructions, combinations and arrangements hereindescribed and claimed.

An object of my invention is to provide a device which may be used as aboomer or a woven wire or a barb wire stretcher, and which whileeifectually accomplishing the purpose for which it lis intended issimple, and is therefore not liable to get out of order.

A further object of my invention is to provide a device which may bemanipulated by one person in the wire stretching operation.

Other objects and advantages Will appear in the following specification,andthe novel features of the devicey willvbe particularly pointed out inthe appended claim.

-My invention is illustrated in the accompanying drawings forming partof this application in which?- Figure 1 is a view showing the use of myinvention, Fig. 2-is a side view of the device showing the method ofoperation, Fig. 3 is a 'plan view of the device, Fig. 4 is a viewshowing another operating position of the device.

In carrying out my invention I provide a main body portion A havingmeans, such as the socket 1, for attachment of a handle 2. The bodyportion A is provided with a slot 3 (see Fig. 3) extending inwardly fromone end and terminates in a pair of hooks or claws 4 and @on each sideof the slot 3. Disposed within the slot 3 is one end of an arm 5 whichterminates in two hooks or claws 5a and 5b.

Embracing the body portion A is a clevis 6, which is rovided at its endwith a ring 7 to which 1s attached a hook 8. A second clevis 9 has itsarms disposed outside of the arms of the clevis 6, and to the clevis 9are bolted the two claws l()a and 10", as shown in Fig. 3. A bolt 11passes through the clevis 9, through the clevis 6, and through the bodyportion A, pivotally securing these together. A similar bolt 11" passesthrough'the opposing arms of the clevis 9, the cevls 6 and the bodyportion A, the bolts 11 and 11 being in alinement but being independent.The arm 5 is pivotally secured to the body portion within the recess 3by means of a pin 12.

From the foregoing description of the varlous parts of the device' theoperation thereof may be -readily understood.

In using thisdevice a link of the chain 19 is inserted between. theclaws 5 and 5" of the arm 5 in the manner shown in Fig'. 2. vNow bypulling the handle into position shown invFig. 1 tension. will beexerted on the chain 17 which will stretch the Wires which are to beattached thereto. The pivot brought above the pivotal portion'll, andtherefore the device remains locked. The operator may now engage thechain 19 with the claws 10a and 10b of the clevis 10, as shown inFig..1. The handle may then be swung into its original position, therebydisengaging the claws 5a and 5b and permitting them to be brou ht intoengagement with another link. handle back again into position shown inFig. 1 the Wire is still further tightened and the claws 10a and 101.may be shifted to another link. Thus the device may be made to graduallystretch the wires to the desired point. It will be observed that eachtime the handle is brought into the position shown in Fig. 1 the deviceis locked so as to ermit the use of both hands in manipulating the claws58L and 5b and 10a and 10b.

The operation described above may be made to pull up eight inches ofslack wire at one stroke. lesser distance the operation is conducted asfollows: The claws 4 and 4b on the end of the body portion A are broughtinto engagement wit-h the chain 19, whenv the handle is moved toward theright instead of toward the left, e'. e., in the opposite direction tothat shown in Fig. 1. This results in the pulling of the Wire until theclaws 5a and 5b may be engaged behind a link of the chain 19, therebycurely.

' I claim:

In a wire stretching device, a body portion provided with a handle, saidbody portion terminating in a pair of claw members,
